At the time I made it I had a sketch from "Mr. Show" stuck in my head where a Good Fellas-esque movie was censored to be shown during the daytime. During one scene it's censored so that the actor says "Mother Father! Chinese dentist." I then learned that Chinese dentist is part of an old bad joke where someone calls in to make an appointment with a Chinese dentist but the person calling in can't get an appointment set up because they keep saying they want to come in at 2:30 but the Chinese dentist says 'I know tooth-hurty, when do you want to come in?' So anyway, to answer your question, I just had the phrase stuck in my head for a while around the time I was making the mix, that's why it's called Chinese Dentist. It doesn't have anything to do with any of the songs, or anything else really.
